TRACK-LEVEL.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed April 19, 1907. Serial No. 369,110.

To all whom "it may concern:

Be it known that'I, BENJAMIN F. YOUNG,

a citizen of the United States, residing at Leavitt, in the county of Haskell, State of Texas, have invented certain new and useful Improvements in Track-Levels and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to track leveling in struments and has for its. object to provide a leveling instrument of this class which may be moved over a section of track to determine irregularities in the roadbed, the rise and fall of the track, and the gage of the rar s.

In carrying out my invention I employ a truck carrying indicating device for indicating the rise and fall of-the track and for determining irregularities in the roadbed, means for indicating the distance traveled which means can of course be used to determine the extent of an rise or fall in the track or roadbed and also the extent of any irregularities. The truck furthermore includes standards which are hinged and are connected by telescopic rods one of which is calibrated so that any deviation from the standard-gage of the track rails may be determined.

In the accompanying drawings, Figure 1 is a side elevation of the instrument, Fig. 2 is a rear elevation thereof, and, Fig. 3 is a detail view of one of the leveling devices employed in connection therewith- In the drawings there is shown a pair of track rails 5 upon which the instrument embodying my invention is desi ned to travel. The said instrument is in the orm of a truck including a top 6 supported by front and rear airs of standards 7 and 8 respectively at the ower ends of which are journaled Wheels 9 which travel upon the said track rails. The rear pair of standards 8 are formed in hinged sections as indicated at 10 and the movable sections of these standards are connected in a mannerwhich will now be described. A sleeve 11 is formed integral with one member 8 and rojects inwardly past the middle of the true and a rod 12 rojects inwardly from the otherof the mem ers 8 and is telescopicallyreceived in the sleeve 11 and is provided with calibrations 13. A set screw 14 is engaged through the sleeve member 11 adjacent its inner end and is ada ted to impinge against the rod 12 to hold t e movable sections of the standards in spread relation and at a degree corresponding to the standard gage of track it being understood that any deviation from this standard gage will cause the rear wheels-either to bind or to tend to leave the track rails.

In order that the irregularities in the roadbed may be indicated, I have rovided at the rear end of the'machine a ca ibrated dial 15 upon the face of which is ivoted a pointer or indicator 16 which is weighted at its lower end as indicated by the numeral 17, this weighted lower end of the indicator serving to normally hold the same in vertical position and in order that any rise and fall in the grade of the roadbed may bedetermined I ave provided a similar indicating device 18 upon one side of the truck substantially at the middle thereof. To further aid in determinin irregularities in the roadbed I have provir ed upon the truck at-itsrear end a spirit level 19.

In order that the distance traveled may be determined, I have provided upon one of the wheels 9 at the rear end of the truck an integral shaft 20 carrying a sprocket gear 21 over which passes a sprocket chain 22. The sprocket chain also passes over a sprocket gear 23 rotatably mounted upon a stub shaft 24 and the said sprocket 23 has formed integral with it a finger 25 which is adapted to contact, at each revolution of the sprocket, with a s ur wheel 26 which forms a ortion of an in icator 27 for indicating the lstance traveled 'by the. truck. I also preferably mount upon the top of the truck-a surveyors level 28.

' What is claimed is 1. A track gage comprising a body, suporting sides hinged to the body and including standards, track Wheels journaled at the lower ends of thestand ards, an .inwardly projecting sleeve member carried by one standard, and a rod carried by the opposing standard and received in said sleeve, the rod being jecting sleeve member carried by one stand- In testimony whereof, I affix my signature, ard, a rod carried by the opposing standard in presence of two witnesses. and 'received in said sleeve, the rod being I BENJAMIN F YOUNG provided with scale marks, and a set screw 5 carried by the sleeve whereby the rod may Witnesses:

be held at adjusted position within the A. TONN, sleeve. 7 EMMET CONDEE.
